gain tans gaunt firm- IMPROVEMENT III LANTERNS.

, SPECIFICATION. TO ALL WHOM IT MAY CONCERN:

Be it 'known that I, RICHARD CHESTER, of Chicago, in the county of Cook,and State of Illinois, have invented a new and useful Improvement-inLanterns; and I do hereby declare that the following is a full, clear, 3

and exact description of the same, refereneeibeing had to theaccompanying drawings, and the letters and figures I i marked thereon,which form part of this specification. I

My said invention consists in arranging, between the case of the lanternand the lamp, a perforated jackegg and connecting therewith an annularsupport forthe glass globe,lhaving.a flange projecting outward to thecase. I of the lantern-above the perforated jacket, so as to cause thewind which enters the ordinaryholes at the sides, to pass thrdughfsaidperforated jacket before coming in contact with the flame, thus breakingand difi'using the I currents ofair and preventing the extinguishing of'the flame. To enable those skilled in the art to understand, how tomakejand use my invention, I will proceed to describe the same withparticularity, making referencein so. doing to theaforesaid-drawings, inwhich- Figure 1 represents aside elevation of my invention. I Figure 2 avertical central section of thesame; and

Figure 3 atop view of the support for the glass globe and its flangeaforesaid. Similar letters of reference in the different figures denotethe same parts of my invention.

A represents the base of the lantern, into which the lamp L is placedthrough the bottom, and secrred by means of the spring catches, S,whichextend over the projection b, as shown. Between the lantern caseand; the lamp is arranged the annular enclosure marked a d, which restsupon the aforesaid projection 6, andiis j j firmly bracedlin the properposition by means of the exterior flange, e, extending out to thecasing, as'shown, The part marked'c is perforated, as shown, while thepart marked cl is not, and the flange or diaphragm, e, causes the airwhich enters through the holes a, in the case, to pass through theperforated jacket, c; to supply the flame with air, while the force of rthe wind is broken thereby, and the extinguishmeut of the flame orlight, p which would otherwise occur, is effectually prevented. 0,represents a second perforated jacket similar to the one marked 0,attached to the diaphragm exterior to the said jacket, 0, which servesmore effectually to break, M I the force of the wind while admitting theair to support the flame as desired. The entiredevice, cc, d,'e, ma'yIbe made removable or permanently attached to the lantern, as preferred.The lower end of the globe enters the support, d, while the upper end issnpportedin the top, 0, as shown. The guards, E, are fastened to thelantern I top, and to a band, E, which is hinged upon one sideto thecase, A, and is secured to the opposite side by a catch, G, so as to beopene'dwhen desired to remove the globe, whose support, however, is notupon the guard band, F, but is entirely independent thereof. Drepresents passages for allowing the heated air .to pass out atthe topof the lantern, while at the same time the wind is directed through thetop without being deflected downward; I upon the flame.

Having described the construction and operation of my invention, I willproceed to specify what I claim and desire to secure by Letters Patent:I

jackets c c, and diaphragm e, arranged and operating as and for thepurposes specified.

RICHARD CHESTER.

I claim the combinationand arrangement, with a lantern and its globe, ofthe globe support d, perforated Witnesses:
